Changeset 30621 for trunk/psModules/src/objects/pmSource.h

Timestamp:

Message:

do not cull peaks with only one entry; skip the section that culls duplicate peaks -- this was dropping many valid peaks and seems unneeded; save radial apertures in their own extension; fixed logic on culling of faint peaks

  *  simplest measurement of a source is the location and flux of the peak pixel
  *  associated with the source:
+ *
+ * a pmSource is the information about a (possible) blob of flux in a specific image.  A source
+ * may represent an insignificant or undetected source.  There may be multiple representations
+ * of an image (eg, alternate smoothed copies); sources on alternate images may have a pointer
+ * to the version on the primary image (source->parent).  A set of sources on different, but
+ * related images (eg, multiple exposures or different filters) which (may) represent the same
+ * astronomical object are grouped together with the pmPhotObj type (set pmPhotObj.h).
+ * 
+ * A single source may be fitted with multiple models (not at the same time!).  The PSF model
+ * fit is a fit of the position (optionally) and the flux to the PSF model at the location of
+ * the source.  Alternate model fits are extended source models. The best model fit is used to
+ * subtract the object from the image.
  *
  *  XXX do I have to re-organize this (again!) to allow an arbitrary set of extended model fits??
